About this game

You know the reason of the world
The journey begins to stop this dreamy, twisted and mysterious 'black sea' here.

In this world where Ichi makes the world and lives in the world's Ichi, a sea in the form of a huge black curtain that appeared one day in the Great Desert of the West.
This 'black sea' is getting closer, devouring everything around it...
Get through this puppet show by defeating visionaries and their inner puppets who use the power of their dreams.

"It's a new doll. It's good to watch"
Step forward with three protagonists with different abilities and strengths in the twisted and dreamy "Black Sea," the magenta flower "Hongdanhyang," the golden hand "Georc," and the dreamer "Eris."

  • Three-person multi-play and maps that require cooperation and strategy
"The price is one thing to dream together."
Play with colleagues who are not alone.
